4 Claims. 1 v This invention relates to a material "moving machine, and more particularly to 'a tpower operated bucket or carrier for such *a machine.

The "object of the invention is to provide a power operated bucket for attachment to a conventional machine, such as a tractor, whereby large quantities of material such as coal or dirt can be handled, moved, or loaded onto a vehicle.

Another object of the invention is to provide a material lifting bucket for a machine wherein the bucket will gradually be tilted as it is raised so that by the time the bucket reaches its uppermost position the bucket will be in dumping position so that the material will be dumped into I a waiting vehicle or the like.

A further object of the invention is to pro- Vide a tractor mounting means which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings,.forming a part of this application, and in which like numerals are used to designate like parts throughout the same.

Figure 1 is a side elevational view of the power operated bucket of the present invention, the bucket being attached to a conventional tractor (broken lines) Figure 2 is a front elevational view of the assemblyof Figure 1.

Figure 3 is a sectional View taken on the line 3--3 of Figure 2.

Figure 4 is a sectional view taken on the line 44 of Figure 2.

Figure 5 is an enlarged sectional view taken on theline 55 of Figure 1.

Figure 6 is a front elevational view of a modiiied'bucket assembly.

Figure 7 is a vertical sectional view taken through the assembly of Figure 6.

Figure 8 is a sectional view taken onthe line 8-8 of Figure 6.

Referring in detail to Figures v1 through 5 of the drawings, the numeral designates one of a pair of horizontally disposed arms which may be made of any suitable material such as steel. The arms 20 are adapted to be connected to a conventional tractor which is indicated by the letter T, the tractor being shown in broken lines, Figures 1 and 2. The rear ends of the arms 20 are adapted to be connected to a horizontally disposed shaft M which extends beneath the I tractor T, and the means for connecting thelarms to the shaft .3! .is indicated Joy-the numeral .32.

The mounting means 32 includes a bracket '33 v '2 which is secured as by welding to the rear-end of the arm '20, and a plate 34 is arranged on the opposite side of the shaft 3| and is connected to the bracket 33 by suitable securing elements such as bolt and nut assemblies 35.

The mounting means'of the present invention further includes an inclined brace "'36 which is arranged on each side of thetractorl', the lower ends of the braces "36 beingisecured as by 'Welding to'the arms '20. Connected to the upper 'end "of each of the braces 3'6, and also connected to the front end of each of the arms "20 is a set of tracks which are indicated by the numeral 3'1. Thus, it will be seen from Figures '2 and 4"that a set of the tracks 31 are varranged on each side of the tractor T at the front thereof.

Each of the tracks3'l comprises a first or inner U-shaped trackway 38 and the U-shaped track 38 opens inwardly toward the tractor T. Each set of trackstl further includes a second .or outer track 39 which also has a U-shape, and the track 39 opens outwardly away :from the tractor t Figure 4. As-best seen in Figures .1 and 3, -.the

tracks '38 and 39 include curved portions, ,so that the movable bucket A0 will :be vin dumping position :by the time it reaches the upper'ends :of the tracks.

The bucket All includes a back wall 4.1 :and extending rearwardly from the back :wall M :is, a pair of spaced parallel vertically l-idisposedzearsifl.

"A pin l lrotatably connects :a .roller 5113 to each .of

the ears .42, and the rollers L43 travel or ride in the inner tracks 38. Alsoextending rearwardly from the back wall-4i is a pair of spaced parallel vertically disposed flanges i5,--and a pin #6 rotat ably connects aroller 4i to eachyof the flanges lfi.

' in Figure '1 to the broken line position shown in "Figure '1 whereby the bucket lfl will be in dumping position by the time it reaches its uppermost position.

"The bucket 49 further includesa bottom wall '48, and extending forwardly from the front edge of the bottom wall 43 is, aplurality .of spaced parallel teeth 49. breaking-up of dirt, or other material which is to be picked-up by the bucket 4J0. A roller 48 is rotatably connected to a pair of spaced parallel arms 149 by a pin 59, the arms 59 being secured to the flange E5 as by welding. The roller 68 also The teeth 39 facilitate .the

rides in the outer track 39, and the roller 48 helps keep the parts in alignment.

A means is provided for raising and lowering the bucket 40, and this means comprises a horizontally disposed bar i which extends between the pair of flanges 45 and is secured thereto. Connected to the bar 5| is a pair of sheaves or pulleys 52, while extending between the upper ends of the tracks 38 and secured thereto, is a U-shaped channel member 53, Figure 1. A pair of pulleys 54 are rotatably connected to the stationary channel member 53, and a cable 55 is trained over the pair of pulleys 54, the cable 55 adapted to be connected to the power take-off mechanism on the tractor T. The cable 55 is also trained over the pair of sheaves 52 which are connected to the bar 5|, and the free end of the cable 55 is connected to an anchor hitch 56, Figure 2. Thus, upon actuation of the power take-off mechanism on the tractor T, the cable 55 will cause the bucket :39 to be elevated, and as the bucket 40 is elevated, the rollers 43 and 4'? will follow or travel the path of the tracks 33 and 39 so that the bucket ll] will move from the solid line position of Figure 1 to the broken line position whereby the material in the bucket will be dumped gradually as the bucket is elevated.

A horizontally disposed beam 5'1 extends between the front ends of the arms 29 and is secured thereto, Figure 3, and a pair of caster wheels 58 are dependingly supported or connected. to the beam 51.

Referring to Figures 6, '7 and 8 there is shown a modified assembly for attachment to the tractor T, and in Figures 6, 7 and 8 the loading bucket is again indicated by the numeral :10, the loading bucket 49 including the back wall 4 1, bottom wall 48 and teeth (not shown). Extending rearwardly from the back Wall 4| are the cars 42 and flanges 45. Rollers 43 and Al are connected to these members, and the rollers 63 are adapted to travel in the tracks 38, while the rollers 47 are adapted to travel in the tracks 39, as previously described. Thus, by the time the bucket 95 reaches its uppermost position, it will have dumped gradually the material that was being lifted.

Extending between the pair of tracks 38 and secured thereto as by welding is a horizontally disposed angle member 6i, Figures 6 and 7. A pair of vertically disposed spaced parallel hydraulic cylinders 59 have their lower ends secured to the beam 51, and a piston rod 50 is slidably or reciprocally arranged in each of the cylinders 59. A hose 62 serves to connect each of the cylinders 59 to a suitable source of hydraulic fluid, and a sprocket 63 is rotatably connected to the upper end of each of the rods 59. A chain 94 is trained over each of the sprockets 53, and one end of each of the chains 64 is connected to the bar 5|. The other ends of the chains 64 are connected to lugs 65 which are secured to the channel member BI. Thus, when hydraulic fluid is supplied to the cylinders 59, the rods 69 will be raised out of the cylinders 59 to thereby raise or elevate the bucket 40.

A horizontally disposed brace 65 extends between the upper ends of the tracks 38 and is secured thereto in order to help maintain the tracks in their proper spaced relation, and extending upwardly from the channel member 6! is a pair of spaced parallel vertically disposed tracks 66. Suitable braces 91 extend between the tracks 66 and 38, and a spaced member 68 is movably arranged in the tracks 66. The spacer member 68 is connected to the sprocket 63 by links 69. A

pair of brackets Ill are connected to the channel member 6! by suitable securing elements such as bolt and nut assemblies H, and the brackets 10 serve to connect the upper ends of the cylinders 59 to the channel member 6|.

From the foregoing, it is apparent that a bucket mounting means has been provided for attachment to a, tractor whereby the loaded bucket of dirt, coal, or other material will be moved to dumping position by the time it reaches the top of the tracks. Thus, as shown in Figures 1 through 5, upon actuation of the cable which is connected to the power take-off mechanism on the tractor, the bucket 40 will be raised and gradually tilted as shown in the three positions in Figure 1. This tilting is caused by the rollers 43 and ll which ride in the tracks 38 and 39, the curvature of these tracks causing the bucket to move into dumping position.

In Figures 6, '7 and 8 there is shown a modified form of the invention wherein the elevation or raising of the bucket 49 is accomplished by actuation of the hydraulic cylinders 59. Thus, upon supplying hyraulic fluid through the hoses 62, the rods will be moved upwardly in the cylinders 59 whereby the chains 64 will raise the bucket 40 and as the bucket 40 moves upward the rollers 43 and 4'! will ride in the tracks 38 and 39 to cause the bucket 40 to tilt and gradually be dumped.
